The 6GT2815-1BN10 is a 10-meter pre-assembled coaxial antenna cable with R-TNC sockets at both ends, built with LMR-300 coax. At 7.62mm OD, LMR-300 strikes a balance between the thin 4.95mm LMR-195 and the heavy 10mm+ LMR-400—it offers meaningfully lower attenuation per meter than LMR-195 while remaining flexible enough to route through standard cable duct.

When should I choose LMR-300 over LMR-195 for a 10-meter run?

At 10 meters and 900 MHz, the attenuation difference becomes significant. LMR-195 at 10 meters introduces roughly 1.7 dB of insertion loss; LMR-300 at the same length introduces roughly 1.0 dB. That 0.7 dB difference translates directly to more forward power reaching the antenna and more backscatter signal returning to the reader. In a passive UHF RFID system where every decibel counts against the link budget, choosing LMR-300 for a 10-meter run can be the difference between reliable tag reads and missed scans—especially at the edge of the antenna pattern or when reading small, poorly oriented tags. If the antenna is within 3 meters of the reader, LMR-195 is sufficient and easier to handle. At 10 meters, step up to LMR-300.

How does this cable compare to the O2YS(ST)CY trailing variant?

LMR-300 is a fixed-installation coax—route it once through conduit or cable tray and leave it. It has lower loss per meter than O2YS(ST)CY of similar diameter. O2YS(ST)CY (6GT2815-2BN15) is for cable carriers and moving antennas. If the antenna is bolted to a fixed structure, use LMR-300. If it is riding on a gantry or robot, use the trailing-rated O2YS(ST)CY.
